accounting machines, the keyboard struccounting mechanism This inventionrelates to and more particularly to tures thereof and to item controlledthereby.

Many types of accounting work require the printing of numerous wholenumber amounts, i. e., amounts having no decimal fractions,interspers'ed with amounts involving decimal fractions. In indexingthese on the well known 10-key type of keyboard, it is necessary todepress the zero key twice following the indexing of the amount, toallocate the digits thereof in correct decimal order (to the left of thedecimal point).

It is an object of the vide a novel keyboard on which either wholenumber amounts or amounts involving decimal fractions may be indexeddirectly in correct decimal order, without it being necessary to depressthe zero key following the indexing of the digits of a whole number.

Another object of the invention lies in the provision of means under thecontrol of the amount indexing keys for counting the number of amountsentered in each of the several accumulating registers.

With these and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts, theessential elements of which are set forth in a pended claims, and apreferred embodiment of which is hereinafter described with reference tothe drawings which accompany and form part of the specification.

GENERAL DESCRIPTION This is an improvement on the machines disclosed inthe applications of Oscar J. Sundstrand, Serial Nos. 581,800 and 88,092,filed December 18, 1931 and June 30, 1936, respectively, now PatentsNos. 2,194,270 and 2,209,240, respectively. The machine is equipped withthe well known IO-key amount keyboard for indexing digits to the left ofthe decimal point in the usual manner, the keys of which will bereferred to as the whole number keys, supplemented by two rows of keysof the 81-key type of keyboard for indexing decimal fractions to theright of the decimal point, these keys being hereafter referred to asthe decimal keys. It is provided with the customary date setting,totalizer and operation controlling keys. Eight adding registers areprovided, four of which are located in an upper group and the other fourin a, lower group. All the registers are actuated by a set of actuatorsadjustable under control of stops set by the amount keys. The actuatorsalso control the adjustment of type for printing amounts and totals Eachregister shaft carries a series of wheels, separate from the amountaccumulating wheels, which count the number of items accumulated in thatregister, separate transfer elements being provided for these itemcounting wheels.

Selection of the registers is performed by depression of one of fourkeys to select a particular register in the upper or lower group, andthe group in which the desired register is located is selected by thedepression of a fifth key.

Totals are taken from the adding registers by depressing the properselecting keys, operating the machine through a blank cycle, thendepressing the register total key and again operating the machine.

The carriage illustrated in the drawings is of the combined front andrear feed type. It is movable laterally to different columns and re-DETAILED DESCRIPTION INDEX or Torres 1. The machine sections and generalactuating mechanism.

1. The machine sectimiis and general actuating mechanism Referring toFigure 1, the machine includes whole number amount keys I and decimalamount keys 2, type bars 3 for printing on work sheets, a laterallymovable paper carriage I mounted on a track 5, and a plate 6 mounted onthe carriage and having a plurality of control magazines 1 forautomatically controlling the operation of the machine in the severalcolumnar positions. The carriage is provided with the customary rollerplaten 8 for insertion of work sheets at the rear thereof, and a bailstructure 9 for use in connection with other sheets fed from in front ofthe platen. Th machine also includes (Fig- 'ure 3) eight addingregisters arranged in two groups situated one above the other, therebeing four registers in each group. They are designated generally A, B,C and D in each group, and each includes a plurality of ten toothedwheels Ill. The last three wheels at the left in each register (Figureare spaced from the other wheels and are numbered I I. These wheels areused to count the items entered in their associated registers.

Manual means for controlling such functions as selection of theregisters, non-addition, total taking, computing selectively in thevarious registers, etc., are located at the right hand side of thekeyboard (Figure 1). The mechanism for performing these variousoperations is fully disclosed in application Serial No. 581,800.

The machine is actuated by an electric motor (not shown). The motor isstarted by the closing of a suitable switch mechanism and is coupledwith an actuating shaft I3 by a suitable clutch mechanism upondepression of a motor bar i4 (Figure 1) The actuating shaft is connectedto the motor drive in such a manner that the shaft is rocked, firstcounter-clockwise and then clockwise, about 90 during each operation ofthe machine.

2. Actuation of registers generally Actuation of the registers iscontrolled by type bars 3 (Figure 3) mounted for vertical movement. Thelower ends of the type bars are each provided with a slotted arm l5,embracing a stud IS on the forward ends of levers l1 pivoted on a rodl8. Strong springs I! are attached to levers l1 and to the machineframe, and tend to rotate the levers clockwise. The levers are normallyrestrained against such movement by their forward arms bearing against arod 20 extending between two spaced, identical cam levers 2| pivoted onrod l8. These cam levers, in turn, are restrained by resting againstrolb 22 on similar spaced arms 23, secured to actuating shaft IS, theshaft being normally restrained against movement as disclosed in myapplication Serial No. 581,800, making the above described mechanismnormally held in the position shown in Figure 3.

The rear end of each lever is provided with a recess 24 in which lies astud 25, there being an increment of lost motion between the parts.Studs 25 are secured to levers 25, also pivoted on rod l8. Springs 21extend between lower arms of levers 26 and the rear arms of levers ll.This spring tension causes studs 25 to be urged toward the upper ends ofrecesses 24. Studs 28 are secured to the rear end of levers 26 and liewithin slots of the lower ends of vertically movable racks 29. The racksare normally held against movement, upward from the position shown inFigure 3, by bell cranks 30 of the transfer mechanism. As explained inmy application Serial No. 581,800, when a transfer occurs between twodenominational orders, the rack 29 affected is released for anadditional step of movement, which causes the rack to be raised to aposition where a shoulder 3| thereon contacts a. guide bar 32, and wherestud 25 lies in the upper end of recess 24. However, since the transfermechanism is identical with that explained in the Sundstrand applicationSerial No. 581,800, it is only necessary to note here that the transfermechanism provided for item counting wheels ll (Figure 5) is independentof that associated with the amount accumulating wheels III of eachregister.

When the machine is operated, roller 22 moves counter-clockwise aboutshaft l3, allowing strong springs I9 to raise type bars 3 and lowerracks 29. The amount of movement imparted to the type bars and the racksis controlled by the amount entered in the keyboard in a manner to belater described. Continued movement of roller 22 raises cam lever 2|,without an accompanying movement of levers l1 and racks 29, after thetype bars are arrested. During the first portion of the return movementof roller 22, it rides along a dwell portion of cam levers 2| to givethe selected register an opportunity to become engaged with racks 29before they return to their raised positions. The ensuing returnmovement of the racks during the return of rollers 22 rotates wheels H)of the engaged register to add thereon the amount indexed.

The lower group of registers are actuated by mechanism identical withthat described in the foregoing, the corresponding parts beingdesignated by like reference numerals with the letter a appendedthereto. A plurality of extensions 33, one for each denominationalorder, are connected to type bars 3 at 34, the lower ends of theextensions each being provided with a slotted arm I50, embracing studs[6a on levers Ila that are similar to levers II. A separate set oftrans- 3. Amount indexing and printing by whole number keys The group oftype bars 3 associated with the whole number keys (Figure 5) areprovided with forwardly extending arms 35 pivoted to the lower ends ofthe type bars (Figure 3). The forward ends of these arms 35 carryupstanding pins 36 arranged to be guided for vertical movement inopenings in a transversely movable slide 31, mounted on a stationary rod38. Pins 36 lie just behind a series of stops 39 and are normallypositioned to the left thereof, as shown in Figure 5. The stops 39 areset, i. e., moved into the path of the pins 36, by depression of theamount keys 40. Depression of the keys 40 thrusts rods 4| (Figure 7)rearwardly, setting the stops. The slide 31 is provided with a forwardlyextending projection 42 having a pin and slot connection with a swingingbracket 43 (see also Figure 5) in which the rods 4| are slidablymounted. Through an cscapement mechanism (not shown) associated with theslide 31, bracket 43, and keys 40, indexing of a number by these keys,as above described, allows slide 31, bracket 43 and pins 36 to move stepby step toward the right, as viewed in Figure 5, one step for each digitindexed, and thereby move pins 36 under the rear ends of the stops 39set by the amount keys. Hence, as the machine is cycled, and the typebars 3 (Figure 3) rise, pins 36 strike against the differentially setstops 39, in which position corresponding type characters in the upperends of the type bars are brought into printing alignment with theplaten 8. Shortly after this, impression hammers 44 are operated toprint the amount. During the last half of the cycle, type bars 3 arerestored as described in the foregoing, and rods 4|, pins 36 and stops39 are restored to their normal positions shown in Figure 5. Any typebars 3 not used in printing this number are prevented from rising by adetent plate 45 (see also Figure .4). The plate 45 is guided for forwardmovement in the machine frame, the forward end thereof being pivoted toan upstanding arm 46 of a ball 41 pivoted on a stationary transverse rod48. A spring 49, secured to the opposite upstanding arm 50 of bail 41,tensions the bail and plate 45 rearwardly so that a shoulder 5| on theplate abuts a portion (not shown) of the machine frame. In thisposition, the rear edge of the plate overlies such of the pins 36 aswere not moved from under the plate when the number was indexed, andthereby prevents the upward movement of the actuators connected withthese mm.

In total taking operations, it is necessary to withdraw this plate fromabove the pins 36 to permit the type bars 3 to rise.

Referring now to Figure 9, the lower end of a register total key 52rests upon the upper edge of a cradle 53 pivoted as at 54. An upstandinglug 55 of a total control slide 56 lies in front of going. A plate I5cradle 53. A depending lug 51 formed on the lower edge of slide 56 liesin backof one end of a lever 58 pivoted at 60 and having its oppositeend resting against a downwardly extending projection 6| secured to thearm 50 of bail 41. Hence, depression of total key 52 withdraws plate 45from above pins 36 againstthe tension of spring 49.

For a more detailed understanding of this indexing and printingmechanism, reference should be made to application Serial No. 581,800.

4. Amount indexing and printing by decimal keys A pair of type bars 3immediately to the right of the whole number type bars (Figure 5) arearranged to print digits to the right of the decimal point, i. e.,decimal fractions. These type bars are connected with the decimal keys 2by forwardly extending arms 62, similar to arms 35, pivoted to the lowerends thereof. The forward ends of arms 62 carry upstanding pins 63,similar to pins 36, that are guided for vertical movement in openings ina tationary guide bar 64 secured on the machine frame. Guide bar 64 ispositioned rearwardly of the decimal keys and pins 63 lie just behindand below a series of slides 65 (Figure 6), the right ends of whichserve as stops. Slides 65 are arranged to be set, i. e., moved into thepath of pins 63 by depression of keys 68 that control the indexing ofthe digits 1 to 9. Keys 68 are suitably guided for vertical movement ina frame 61, and each key has a slot and lug connection with a bell crank66 pivoted on the side wall of the frame. Slides 65 are pivoted at theirleft ends to bell cranks 66, and springs 69 mounted between shoulders onthe slides and a flange on frame 61 normally tension the slides towardthe left, and the corresponding keys toward raised position as shown inFigur 6. A locking zero stop slide 10 is slidably supported in frame 61beneath slides 65 and serves to stop the upward rise of pins 63 andtheir associated type bars 3 in position for printing zeros when nodigit "1 to 9 is indexed. This slide has a series of upstanding bevelledlugs ll contacting bevelled surfaces of lugs 12 formed on each of thekeys 68. Springs 13, connected between the right ends of slides 10 andframe 61, normally tension the slides toward the right as viewed inFigure 6, so that extensions 14 thereon normally overlie pins 63.Clearance between the upper ends of pins 63 and the lower edge ofextensions 14 provides for the upward movement of the type bars to zeroprinting position.

Depression of a key 68 causes its lug 12 to cam the associated slide 10toward the left, whereby extension 14 is withdrawn from the path of pin63 as slide 65 corresponding to the digit indexed moves to the rightinto the path of pin 63. The parts are locked in this position by lug 12of the depressed key engaging a shoulder 74a provided on thecorresponding lug 1|.

When the machine is then operated, the type bars 3 rise, and pins 63strike the ends of the differentially set slides 65, in which positioncorresponding type characters on the upper ends of the type bars arebrought into printing alignment with the platen 6. As was described inconnection with whole number printing, impression hammers 44 (Figure 3)aretripped shortly after this to print the amount.

During the last half of the cycle, type bars 3 and pins 63 are restoredas described in the fore- (Figure 6) extending transversely of themachine is pivoted as at 10 on frame 01. The lower edge of this platelies immediately behind upstanding lugs 11 formed on the left ends ofslides 10. By this arrangement, a slight clockwise movement of plate 15about its upper edge (as viewed in Figure 6) at the end of each machinecycle pulls slides 10 to the left sufficiently to release any depressedkey 88 and its associated slide 65. The key restoring mechanism isidentical with that disclosed in detail in application Serial No.581,800.

It is essential that slides 10 be withdrawn from the path of pins 53 fortotal taking operations, so that their associated type bars can rise toprint under control of the decimal fraction wheels of the selectedregister. This withdrawal of slides 10 is controlled by mechanismassociated with the register total key (Figures 9 and 10). The mechanismincludes a link 18 supported for sliding movement on rock haft I3, andon a stud 80 secured in the machine frame. A strong spring 8I normallytensions the link forwardly, causing an upstanding arm 82 thereon tobear against a roller 83 on a plate 18 secured to shaft I3. A lever 84pivoted on a stud 05, secured to the machine frame, is provided withhooks 88 that engage slots in the forward ends of slides 10. The freeend of lever 84 lies directly in front of the forward end of link 18,and is tensioned toward the link by a spring 88 connected between thelever and the machine frame. A spring tensioned latch 80 pivoted on studhas a flange 8I arranged to engage a shoulder 8 la on the lower edge oflink 18. Latch 80 is provided with a depending arm 83 that lies directlyin front of an extension 84 secured as at 85 (Figure to total controlslide 06.

Depression of total key 52 to condition the machine for total takingmoves slide 58 forwardly, as before described, causing extension 84 tostrike arm 83 of latch 80 and rock the latch clockwise about stud 80 adistance suflicient to remove flange 8| from engagement with shoulder8Ia.

Total key 52 is held depressed by a lock slide (not shown) similar tothe lock slides 10 associated with the decimal keys. This holds theparts in the position above described, with link 18 free to move forwardunder the control of roller 83. When motor bar I4 is then depressed,initiating the total taking cycle, shaft I8 rocks counter-clockwise,moving roller 88 away from arm 82 and thereby permitting link 18 andlever 84 to move forward under the tension of spring 8|, this springbeing superior to spring 88. This withdraws slides 10 from the path ofpins 03 during the first part of the cycle. The decimal type bars arenow free to rise differentially under the control of the decimalfraction wheels of the selected register. After the type bars are raisedand the impression hammers 44 operated to print the total, rock shaft I3and roller 83 swing clockwise, roller 83 moving link 18 back to itsnormal position shown in Figure 9 by striking arm 82. At the completionof the cycle, key 02 is restored in the usual manner, permitting flange8 I to again engage shoulder 8Ia of link 18 to prevent the link fromcoming forward during ensuing accumulating operations. During therestoring movement of link 18, slides 10 are returned by springs 18 totheir normal position where extensions 14 overlie pins 08.

Slide 56 may be actuated under the control of the traveling papercarriage 4 to automatically condition the machine for total takingoperations.

aaoaaea Referring to Figure 10, the rear end of the slide rests againsta depending arm of a lever III pivoted on a stationary rod I80. LeverI02 is arranged to be actuated by a rod I04, resting thereon and guidedfor vertical movement in the machine frame. Rod I04 is arranged to bedepressed by a control lug placed in magazines, such as 1, supported onthe control plate 8 of the carriage in columns where register totals areto be taken. As the carriage moves into these columns. a lug, such asI00, depresses rod I04 and rocks lever I02 clockwise about rod I03 tothrust slide 00 forwardly to condition the total taking mechanism.

5. Carriage controlled means [or non-printing .00 in whole number amountcolumns As it is undesirable to have .00 printed in those columns of thework sheet allocated to the printing of amounts not containing decimalfractions, the following means is provided to suppress this printing.

A non-print plate I06 (Figure 10) is pivoted on a stationary rod I01,and has a downwardly turned flange I08 along its rear edge of sufllcientwidth to engage the impression hammers 44 associated with the decimalfraction type bars. A link I08 is pivoted at its upper end to the plate,extends rearwardly and engages a depending arm I I0 of a lever IIIpivoted on rod I08. A rod III similar to rod I04 rests upon thehorizontal arm of this lever and is guided for vertical movement in themachine frame. Rod III is arranged to be depressed by lugs such as I I0placed in magazines 1 for the columns in which whole numbers areprinted. A spring I I4 secured to lever I08 and to the machine framenormally tensions the link rearwardly and maintains the associated partsin the position shown in Figure 10. When the carriage tabulates to thecolumns where a whole number is to be printed, lugs III depress rod III,rock lever I I I clockwise, and thrust link I" forward against thetension of spring I I4. This forward movement of link I08 rocks plateI00 downwardh' and thereby lowers flange I00 into the path of hammers 44associated with the decimal fraction type bars I to prevent the hammersfrom striking the ".00 type when either an item or a total is printed inthese columns.

6. Item counting mechanism and control thereof by whole number keys Asbefore stated, each register is provided with three adding wheels II(Figure 5) for counting the number of items indexed on the amountindexing keys I and 2, for accumulation in the selected register. WheelsII are actuated by racks 28 associated with item count type bars 8located to the left of the whole number type bars. These type bars haveforwardly extending arms IIO, similar to arms 30, pivoted to the lowerends thereof (see also Figure 4). The forward end of arm I I5 connectedwith the units item count type bar carries an upstanding pin I I8 guidedfor vertical movement in an opening in slide 81 to the left of pins 38.The forward ends of arms I I8 associated with the tens and hundredsorders of the item count type bars carry upstanding pins II1 arranged tobe guided for vertical movement in openings in a stationary guide IIIsupported on rod 88 to the left of slide 81. A detent plate III, similarto detent plate 40, normally overlies pins I I1 to prevent the upwardmovement of their associated type bars beyond zero printing positionduring item entering operations.

Thepin III isshorterthanpinsfl," and III,

and lies below a detent I20 that is mounted for forward and rearwardsliding movement-below detent plate 45, in a recess I2I provided inslide 31 as shown in Figure 4. A screw I22, passing through a slot indetent I20 and secured in the machine frame, serves to guide the detentand secure it within recess I2I. The distance between the upper end ofpin H6 and the under side of detent I 20 (Figure 8) is suiiicient topermit the units item count type bar to rise to zero printing positionduring each cycle of the machine.

When, however, an amount is indexed by the whole number keys I, indexingof the first digit thereof causes slide 31 to move one step toward theright, as described in the foregoing. This step of movement withdrawspin I I6 from its position beneath detent I20. It still lies underdetent plate 45, however. Now, upon cycling the machine to accumulatethe amount indexed, pin I I6 rises until arrested by plate 45. Thisamount of movement is suflicient to allow the units item count type barto rise to its 1 position, and its associated rack 29 to descend adistance of one tooth. Following the release of the impression hammers44 to print the count 1 and the amount of the item, the selectedregister is engaged, and, when the rack 29 ascends during the latterhalf of the cycle as type bars 3 are restored, "1 is added in the unitsorder wheel of the item count wheels II. Transfer mechanism identicalwith that shown in Figure 3 is provided for the item count wheels, sothat when a transfer occurs between two denominational orders in itemcounting, the rack 29 affected is released to impart an additional stepof movement to the wheel I I of the next highest order.

7. Control of item count by decimal keys Mechanism is provided under thecontrol of the decimal keys 2 for withdrawing detent I20 from over pin IIE to effect an item count of the amounts that do not involve wholenumbers, but which are indexed by the decimal keys 2 alone. Thismechanism includes a plate I24 (Figures 4 and 8) pivoted on screws I25along its right edge and lying directly beneath the lower ends of thekey stems 68 of decimal keys 2. A pair of springs I26 (Figures 4 andconnected between the left edge of the plate and the machine frame,normally tension the plate upwardly, so that its upper surface restsagainst the lower ends of the left row of decimal keys 2, as shown inFigure 8. A slide I21 (see also Figure 4), lying under bail 41, isarranged for transverse sliding movement upon screws I28 passing throughslots therein and secured in the machine frame. Slide I21 carries anupstanding projection I29 having a beveled edge I30 at its upper endarranged to bear against the left edge of plate I24 under the tension ofa spring I3I connected between slide I21 and the machine frame. The leftend of slide I21 is provided with a pin I32 embraced bv a slot providedin one arm of a bell crank I33 pivoted on a screw I34 secured in themachine frame. The opposite end of hell crank I33 rests against adepending lug I 35 pivoted on rod 48 and secured at its upper end to anarm of a bail I36 also pivoted on rod 48. The opposite arm of bail I36is pivoted at I31 to the rear end of detent I 20. A spring I43,connected between the arm and the machine frame, normally tensions thebail clockwise about rod 48 so that lug I35 rests against bell crank I33and detent I overlies pin II6.

By this construction, depression of any decimal key 2 rocks plate I 24downwardly against the tension of springs I26 and cams slide I21 towardthe left. This movement rotates bell crank I33 clockwise about pivot I34, swings bail I36 counter-clockwise about rod 48, against the tensionof spring I43, and withdraws detent I20 from above pin II6. Pin H6 isnow free to rise one step, as explained above, to enter 1 in the unitsorder wheel of the item counting wheels I I.

Look slides 10 hold the decimal keys depressed and the associated trainof parts in the positions above described until near the end of themachine cycle, at which time restoring plate 15 (Figure 6) is actuatedto allow the depressed decimal keys 2, plate I24, slide I21, bell crankI33, bail I36 and detent I20 to return to their normal positions shownin Figure 4.

It is necessary that detent I20 and detent plate I I9 be withdrawn fromabove the pins H6 and H1 simultaneously with the withdrawal of detentplate 45 from pins 36 during total taking operations, in order that theitem count type bars may rise to print a total.

To provide for this, a ball I38 (Figures 8 and 9), similar to bail 41,is pivoted on rod 48 adjacent bail 41, and is connected for movementtherewith by means of a screw I39 (Figures 4 and 8) passing through arm46 of ball 41 and secured in an upstanding arm I40 of bail I38 (Figure8). The opposite upstanding arm I of bail I38 is pivoted at I42 to aforward ex tension of detent plate I I9. The base of bail I38 liesimmediately in front of lug I fixed on bail I36. Hence, depression oftotal key 52 moves not only bail 41 and plate 45, but through screw I39moves bail I38, plate H9, and detent I20.

I This permits a total tobe printed from the item counting wheels II aswell as from the amount wheels I0.

8. Illustration of printed items and totals In Figure 11, the number Ion the top line represents the item count, and the number 25I 2represents a whole number item. The numbers on he second line show theprinting of a total taken from one of the registers used foraccumulation of whole number amounts, the number 21 representing thenumber of items that have been entered in the register and which havebeen accumulated to give the total 254368.

The third line represents an item having a decimal fraction. The numberson the fourth line show the printing of a total taken from one of theregisters used for accumulation of amounts having decimal fractions, thenumber 31 representing the number of items entered in the register, andwhich have been accumulated to give the total 452651.29.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment therein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
